Following an Aug. 19 train derailment, in which a passenger car went off the tracks two blocks east of Montclair's Walnut Street station, New Jersey Transit crews were dispatched to perform track repairs, which caused delays and cancellations for the entire line.

The emergency work, which occurred between the Bay Street and Montclair State University Stations, was slated to last until Sept. 8, but the agency revised the completion date on Saturday.
